Two radius ideas, never one vague label
A 29-wide footprint has geometric radius 14.5, yet its furthest block center is 14 steps from the center block. The minecraft circle calculator labels both values.
SURVEY DESK / LIVE BLOCK LEDGER
Plan the footprint before the first block. This minecraft circle calculator keeps diameter, two radius meanings, rows, anchors, materials, and world positions on one sampled grid. Switch between outline and filled, then take calculated coordinates into your build.
Radius and diameter stay linked. Editing either field immediately rebuilds every count, run, anchor, and export.
Stack math applies only to the standard full blocks in this selector. Items with other stack limits are not represented.

Scroll the range or toggle overlays; the drawing, labels, and ledger respond to the real plan.

Field method / 04
Enter occupied cells across, or use radius from the center line. Odd results own one center block; even results surround a gap. The linked field exposes rounding immediately.
Use outline for rings and walls or filled for floors and platforms. Both totals remain visible. The active mode alone drives resources, rows, coordinates, and export.
Add X, Y, and Z. North is negative Z, east positive X, south positive Z, and west negative X. Check all four anchors before following long arcs.
Select a full block and layer count. Read stacks of 64, remainder, and slots. Copy positions or download JSON with inputs, runs, anchors, and both coordinate forms.
Calculator-specific value
A 29-wide footprint has geometric radius 14.5, yet its furthest block center is 14 steps from the center block. The minecraft circle calculator labels both values.
Odd diameters put relative 0,0 on a block. Even diameters surround a gap; an adjacent integer cell becomes reference while the mathematical center stays half a block away.
The active footprint is multiplied by layers and split into stacks of 64 only for selected standard full blocks. Tools, signs, buckets, and differently stacked items are excluded.
Cells are deduplicated before totals or exports. Relative and absolute base lists therefore equal the active cell count, including cells on mirrored center axes.
Intent separation
| Size meaning | Linked footprint diameter, geometric radius, and center-to-block reach | A width control without a site-survey explanation |
|---|---|---|
| Center decision | Explicit odd block or even gap, preserved in coordinate output | A centered preview that leaves the in-world origin implicit |
| Resources | Outline and filled totals plus layers, stacks, remainder, and slots | A visual count that still needs manual multiplication |
| Placement | N/E/S/W anchors, row runs, and absolute X/Y/Z cells | A picture that must be translated by hand |
Invariant ledger
Candidate block centers are tested against the radius. Filled comes first; outline keeps filled cells with an open cardinal neighbor.
Sorted Z rows make X runs and extreme anchors. Adding the world center changes positions, never membership or counts. Every surface uses this function.
The input follows block centers; geometric radius is half the footprint width. For 29 cells they are 14 and 14.5.
It is the gap between four blocks. Export uses an adjacent integer reference and records the half-block offset.
Yes. Outline filters filled cells for exposed four-way neighbors. A coordinate cannot appear in outline unless it already exists in filled.
No. The ledger covers selected standard full blocks that stack to 64. Do not apply it to signs, tools, snow layers, buckets, or other inventory rules.
JSON records geometry, center, mode, material, layers, resources, anchors, runs, and both coordinate lists. It claims no command compatibility.
Set the real center, choose the active construction mode, and let the minecraft circle calculator produce a ledger you can audit cell by cell.
